Black Hole Data Pack (1.18.2, 1.17.1) introduces the singularity into Minecraft. The singularity, when placed down, will start to absorb everything around it to become stronger. As it gets stronger, so does its suction. It will eat everything until there’s nothing left. Any mob or block near it will be sucked up and die (except for the player). When two singularities are placed closed to each other, they will combine to make a stronger one. The singularity can also absorb blocks such as bedrock. To remove the black hole, you can right-click the center of it. Have fun!
